Definitions

  • the present invention relates to brassiere cups, and more particularly, to brassiere cups incorporating padded underwire assemblies having gel pads and a method of making the same.
  • Brassieres are undergarments for covering, restraining, shaping, and elevating the wearer's breasts. Brassieres are designed for specific body types, fashions, and activities. Common brassiere styles include full-coverage, push-up, padded, demi cup, plunge, multi-way, strapless, racerback, backless, and front closure. Regardless of the styles and types, brassieres often contain cups with underwires for added effects of shaping, lifting, and supporting the breasts. In some instances, brassiere cups are integrally attached to garments, such as tank tops, shirts, dresses, or bathing suits.
  • the underwires in brassiere cups extend partially or entirely along the lower periphery of the cups and are positioned in a sleeve disposed about the lower periphery of each brassiere cup.
  • underwires are molded between layers of brassiere cup materials.
  • Underwires are generally formed of thin lengths of a fairly rigid material, such as metal or polymeric material, having a rectangular or rounded cross-section. The rigidity of the underwire material is essential for lifting and holding the breasts in place. At the same time, the materials must be flexible enough to curve along the bottom contour of the breasts, which is a generally a widened U-shape.
  • underwires While underwires have achieved widespread usage, certain disadvantages result from their use.
  • the underwires apply pressure to the wearer along the lower periphery of the brassiere cups.
  • the ends or tips of the underwires create the greatest pressure on the wearer.
  • Such pressure points are located at areas on both sides of the breasts proximate the wearer's armpits and areas in between the cleavage portion of the breasts.
  • the pressure results in rubbing or pinching of the skin—rendering prolonged use of the brassiere uncomfortable or even painful.
  • the underwire tips could tear through the brassiere materials and partially expose the underwire as a result. If the exposed underwire tips are hard or sharp, they could scrape or puncture the clothing or skin of the wearer. Even if no such damages occur, the exposed underwire could cause skin irritation to some wearers due to an allergic reaction, especially when the underwire is made of metal.
  • a common practice for alleviating discomfort from brassiere underwires is to provide a cushion along the entire length of the underwire.
  • Such cushions are often made of a soft foam, cotton, or layers of fabric.
  • This solution helps to reduce the overall pressure, it does not effectively balance the uneven pressure created by the underwire tips.
  • the bulkiness of the cushion creates a space between the wearer's breasts and the brassiere—rendering the brassiere more prone to being displaced with movements of the wearer.
  • the cushions may also cause brassiere to appear heavier and bulkier, which may interfere with fashionable outer garments. Therefore, such wearability problems are undesirable, both from practical and aesthetic perspectives.
  • underwire end protectors For example, a cushion tip made of a relatively soft material, such as plastic, can be attached at each end of the underwire.
  • this solution too encounters problems. Since the end protectors are softer and more fragile than the underwire, there comes a point where the end protector breaks. This occurs when the brassiere is subjected to repeated use and wear created by the movement of the wearer. When the end protector reaches its stress threshold, it breaks and exposes a portion of the metal underwire.
  • Some manufacturers have tried to solve this problem by completely encapsulating the underwire with more material such as rubber or foam. Again, the added materials cause displacement of the brassieres or undesirable bulkiness, resulting in wearability problems.
  • underwire brassiere cups that overcomes some or all of the previously delineated drawbacks of prior underwire brassieres. Particularly, there is a need for underwire brassiere cups that minimize wearability problems and painful pressure points on the body of the wearer, while also providing support and rigidity to the wearer.
  • An object of the invention is to overcome the drawbacks of previous inventions.
  • Another object of the invention is to provide novel and useful brassiere cups having gel tips that increase the comfort and wearability to the user.
  • Another object of the invention is to provide novel and useful brassiere cups having gel tips that are formed into desired shapes.
  • Another object of the invention is to provide underwire gel tips for reducing the pressure associated with the tips of the underwire on the body of the user.
  • Another object of the invention is to provide novel and useful underwire assembly comprising an underwire and gel pads coupled thereto.
  • a brassiere cup for protecting a wearer which includes gel tips.
  • Gel tips are protrusions formed by placing at least one gel pad between inner and outer layers of materials.
  • the inner layer includes at least one shaved gel area to house the at least one gel pad.
  • the gel tips are strategically placed on the brassiere to alleviate pressure points created by the brassiere.
  • an underwire assembly comprising an underwire having an arcuate wire coupled to at least one gel pad.
  • the arcuate wire is housed in a wire casing before the at least one gel pad is attached.
  • the tips of the arcuate wire may be covered with protective paint or caps known in the art before it is housed in the wire casing.
  • the at least one gel pad is preferably attached to either end of the arcuate wire. But the gel pad may be attached anywhere along the length of the arcuate wire and need not cover the entire length of the arcuate wire.
  • At least one gel pad is attached to each end of the arcuate wire on a surface that faces the body of the wearer and each end of the arcuate wire roughly corresponds with the center of the at least one gel pad.
  • the underwire assembly is then incorporated into a brassiere.
  • a protective brassiere cup comprising an underwire assembly and an inner layer attached to an outer layer.
  • the inner layer comprises an inner foam material that is substantially laminated to an inner fabric lining.
  • the outer layer comprises an outer foam material that is substantially laminated to an outer fabric lining.
  • the underwire assembly has an arcuate portion coupled to at least two gel pads. Each of the gel pads are coupled, to respective ends of the arcuate portion.
  • the underwire assembly is preferably housed between the two foam layers at around a lower peripheral area of each brassiere cup.
  • the properties of the material used to make the gel pads allow the gel pads to absorb and redistribute the pressure from the underwires.
  • the gel pads according to the present invention balance the uneven pressure exerted by brassiere cup or underwires by providing maximum support and cushioning effect.
  • the wearer is able to enjoy the benefits of a brassiere, including an underwire brassiere, without the fear, discomfort and/or pain associated with it.

  • a “brassiere” refers not only to an undergarment, but also an integral piece of a garment to support and give contour to the breasts.
  • Examples of such garments include, but are not limited to, shirts, tank tops, camisoles, other conventional tops, dresses, leotards, sportswear, bathing suits, and the like.
  • the term “inner layer” of a brassiere refers to the layer that adjoins the body when a wearer wears the brassiere. Accordingly, the term “outer layer” refers to the layer that is further away from the body of the wearer.

  • gel tips 125 and 130 include integrally placed gel pads on an arcuate wire of the brassiere cup 110 . Since gel tips 115 , 120 , 125 , and 130 do not cover the entire length of the underwire, the brassiere cups 105 and 110 sit closer to the body of the wearer.
  • the gel tips according to the present invention minimize the chances of the brassiere cups being displaced. Furthermore, while providing cushion, the less bulky appearance of the brassiere cups of the present invention allows the brassiere cups to be worn under many fashionable outer garments. It must be noted that although FIG. 1A shows a preferred embodiment with four gel tips 115 , 120 125 , and 130 placed at locations corresponding to all four ends of the arcuate wire, not all ends of the arcuate wire need to have a gel tip. Thus, it is conceivable that only one end of the underwire has a gel tip according to the present invention. Moreover, it should be appreciated that gel tips may be placed on other parts of the underwire and/or other parts of the brassiere to minimize pressure points from the brassiere.
  • the gel pads are not visible from the back side of the brassiere as they are covered by the inner layer.
  • the volume of gel pads may cause the formation of protruded gel tips on the surface of a brassiere cup.

  • the gel tips 115 , 120 , 125 , and 130 as shown in FIG. 1A all have tear-drop shapes, because the corresponding recessed areas of the second molding panel also had indented tear-drop shapes.
  • the integrally molded composite layer comprising the outer layer 205 and the composite inner layer 720 is trimmed to remove the excess material and create brassiere cups 105 and 110 .
  • the cups 105 and 110 are preferably smooth with no apparent bumps visible on the front side 220 .
  • the back side of the brassiere cups 110 and 105 preferably bear protruded gel tips 115 , 120 , 125 , and 130 .
  • the bulk of the gel pad material 400 is present on the first side 430 of the arcuate wire 405 , so that the wearer of the brassiere cups will have a maximum support from the gel tips by having more gel pad material 400 closer to her than on the opposing second side of the arcuate wire 405 .
  • the brassiere cup assembly according to the present invention may be further incorporated into brassiere products known in the art including undergarments, garments such as tank tops, camisoles, other conventional tops, dresses, leotards, sportswear, bathing suits, and the like. As such, the brassiere cup assembly may be attached to conventional brassiere components such as hooks, straps, fabric, or other auxiliary components to produce a final brassiere product.
  • a cross-sectional view of the shaved gel area 320 as shown in FIG. 10 provides a clear view of the configuration of various components in the area proximal to the shaved gel area 320 .
  • the configuration is also applicable to other shaved gel areas according to the present invention.
  • the wire casing 425 contains the arcuate wire 405 , whose end 410 aligns approximately with center point C of the gel pad 400 .
  • the underwire assembly 420 rests on the polyurethane foam material side 225 of inner layer 210 . More specifically, the underwire assembly is placed such that the gel pad 400 is housed within the shaved gel area 320 .
  • the polyurethane foam material 225 of inner layer 210 faces the polyurethane foam material 215 of the outer layer 205 . This ensures that after the second molding process the brassiere cup portions 610 and 615 , which correspond to brassiere cups 110 and 105 , respectively, will have the back and front sides bearing fabric linings 230 and 220 , respectively.
  • the gel tips according to the present invention may be formed of various shapes. Examples of such shapes include, but are not limited to, a circle 1005 , an oval 1010 , a triangle 1015 , a heart 1020 , a small triangle 1025 , a half-circle 1030 , a half-oval 1035 , a tear-drop 1040 , and a small heart 1045 . It should be appreciated that the shape of shaved gel areas as well as bulged and recessed areas of the molding panels may be modified to form the desired shapes for the gel tips. All other aspects of the invention may remain the same as the embodiment shown and described in FIGS. 1-9 , without departing from the scope of the invention.
